IMPROVEMENT IN MOLDS FOR FORMING- '.lll-ie Schedule referred to in theseLetters Patent and making of the same.'

To all 'whom it may concern:

Be it known. that I, J osnrn EDWIN'WARD, of Bredbury, in the county ofChester, Kingdom of Great Britain, have invented certain new and useiiilImprovements in Machinery for the Manufacture of Hats, or other likehead-coverings, of which th'e following isa full, clear, and exactdescription, reference being had to the accompanying drawing, formingpart oi' this specification, and in whioli`-,

Figure 1 represents a partly sectional elevation oi' a machine orapparatus lfor making hats, constructed in accordance with myimprovement;

Figure 2,'a plan of the same, with the pipe which conveys the waterunder pressure tothe mould or elastic bag or medium contained therein,broken away or in section; and

Figure 3, an 'elevation of. the mould as or before itv 'is divided. p

Similarletters of reference indicate corresponding parts.

This invention relates to machinery to be used for moulding or pressinga certain form of felt and other hats; that is, such as will notwithdraw from the mould when pressed into the shape desired.

The meansvby-whichthe pressure upon the hat is etl'ected is or may besimilar to that used for pressing hats which will Withdraw from themould when iin- 'ished, namely, hydraulic pressure, acting through anelastic lining, bag, or medium, and the case containing the mould heatedby steam; but in this, my improvement, the mould in which the hat isl tobe pressed is formed in halves, or two equal sections, which are heldtogether when the 'hat is being pressed, and separated when the hat isto be removed, one part ofthe mouldcase and mould being iixed and firmlysecured to the bed or frame, while the other part of said case and mouldis arranged to slide, so that it may be set by a screw, or itsequivalent, to meet or Withdraw from the fixed portion of the' case andmould, and when adjusted to meet, be. suitably or securely locked;A alsoboth divisions of the mould-case having' steam separately conveyed tothem, with orundcr suitable provision for adjustmentfof the movableportion of the case.

The invention consists in a peculiar construction of the mould, which isfirst cast as a complete mould,`

'scribed here.

or portion of the case is arranged to slide in a groove,

a, to orfrom the fixed' half B, by means of a screw,

0provided with a locking-screw, '11, to hold the movable section inplace when setup against the fixed portion.

instead of, the screwO, any other suitable means maybe employed foreiiecting the movement or arljustlnent of the mould-case section B. v

Each halt' B B'of Ythe mould-case is Amade hollow, and heated by steam,introduced by separate pipes or branches D D', the one at least ofwhich, namely, the one supplying the movable portion ,B of the case,

should be of such length to admit of it springing when moving saidcase-section, or it may be ited with a swivel or other joint, that willallow of such play of the mould-section without` injuriouslydisturbing-or breaking the connection, j

Condensed steam may be drawn off from each vhalf of the mould-case bypipes E E, that should be 'fitted with taps or cocks. l

The moulds, or mould-sections, F F', for different sizes oi'A hats, areall of the sa1ne`size externally, and lit into the interior of the caseor case-sections B B.

The construction of the cover to the hat-mould or moulds, and thehydraulic apparatus, and its mode of action, being well known, need not`be minutely de- I will therefore only naine some of such parts.

Gr is the cover, to which the elastic bag d is secured. e isla rod,passing through a. guide, f, for lifting the cover. Gr.

This rod eis attached to one end of a chain or cord,- passing overpulleys q g, and to the other end of said chain or cord imbalance-weightis attached.

-H' is the pipe from the hydraulic reservoir to a twoway cock, I, fromwhich it ascends the, pipe H, -auddescends the` pipes lH2 H3 to theinterior of the elastic bag d.

The pipe H3 is secured to the cover G, and slides through a gland intothe pipe H2 when the cover is lifted.

J is the pipe'for conveying away the Water from the elastic bag d; l

Kis a tap, forallowing the 'air to escape from the elastic bag. l

I L is a locking-brace, centred upon .the rode, and

turned to lap under hookse', when it' is required to establish the lockof the cover. v

The two-way cock I is so constructed and operated as that it is, or maybe, always open to the pipe H, and in through communication either withthe inletpipe H or Waste-water pipe .T, accordingly as-it is requiredl.to enter or discharge water into or nom the elastic bag.

The mould-sections F F are made in one piece, or

entire, as represented in fig. 3, with a, chin portion, my,

v down opposite sides of it, and thus constructed whole,

the mould is turned or finished externally :md internally, andaferWzu-ds broken :itt-he reduced portions m, so as to give jagged orragged instead of stmight edges to the two mould-sections F F', asrepresented in Iig. l, and which avoids marking the hat.

What is here claimed, and desired to be secured by Letters Patent, is

The would F F,ooust1'i1cted perfect, o1' entire, with :1- rednotion, m,where it is required t-o establish the joint, so as to form 1i jagged.or ragged fracture when separat-ing the mould into sections, essentiallyas and for the purpose herein set forth..
